Father making a stink about island national (9)
I believe the answer is:
pakistani
'national' is the definition.
(I've seen this before)
'father making a stink about island' is the wordplay.
'father' becomes 'pa' (pa can mean dad or father).
'making' indicates anagramming the letters.
'about' is a charade indicator (letters next to each other).
'island' becomes 'i' (geographical abbreviation).
'a'+'stink'='astink'
'astink' put after 'i' is 'iastink'.
'iastink' with letters rearranged gives 'kistani'.
'pa'+'kistani'='PAKISTANI'
(Other definitions for pakistani that I've seen before include "from 16 [ISLAMABAD], perhaps" , "E.g. someone from Islamabad" , "Nationality of citizen of Islamabad" , "Asian" , "Oriental" .)
